Reaction Steps

(2-Amino-5-(trifluoromethyl)phenyl)(phenyl)methanone (300 mg, 1.13 mmol) and 2-(1H-tetrazol-5-yl)acetic acid (145 mg, 1.13 mmol) were suspended in ethyl acetate (10 ml). Then 1-propanephosphonic acid cyclic anhydride (2.02 g, 1.89 ml, 50% solution in EtOAc, 3.18 mmol) was added and the mixture was heated to 50° C. overnight. Then water was added at room temperature and the resulting precipitate was filtered, washed with water and heptane and dried at 50° C. and 15 mbar to afford the title compound (380 mg, 94%) as yellow solid. MS (ESI): 356.5 (M−H)−.
